Sounds like either a bug in Bison, a bug in M4, or a mismatch between the Bison and M4 on your system.  See some of the 
things a search for

        "/usr/bin/m4: ERROR: EOF in string" bison

finds; for example

        http://archives.postgresql.org/pgsql-hackers/2004-04/msg01012.php

says

        I'd say you have a broken bison installation; or possibly bison is okay but m4 isn't (recent bisons depend on 
m4, and I think require it to be reasonably late-model gnu m4).-
